@sg said in [The native L1+L2+Select+Start combo option to show menuI read some posts that combos are not possible,
I know you solved the post but wanted to mention that the reason changing hotkey combos permanently is not really supported is because the buttons are assigned dynamically to the Retroarch “Retropad” (virtual controller) by the ES front end configuration menu item.
So the button numbers can sometimes change drastically across controllers (e.g. 2 button NES vs PS3 pad). I think the “configgen” script in Recalbox handles ES->Retroarch mapping - if you want to poke around on the Linux side of things.
